|Z. haageana is one of the outstanding annuals prized for its profuse display of stunning summer flowers. Erect, bushy annual with linear or linear-lance-shaped leaves to 3 inches long and coated with bristley hairs. Produces daisy-like flowers with broad petals. Thrives in sunny areas. Ideal for annual for the beginner. A must for the cutting border. Powdery mildew can be a problem in humid areas such as the South. Plants started from seed around the 4th of July seem to have less of a problem. Remove spent flowers to encourage new blooms.
